This was nicely scoped for a jam. Though the levels are much more simple and self-contained, I feel like there's some good variation in the movements that the player is being asked to do across the game.
The way the physics engine is used is a little rough around the edges - the player passes slightly into level the floor/ceiling/platforms when landing, and getting stuck on walls when pressing against them while falling feels like it works against the kind of experience that the game is trying to convey.
Short and sweet, and it's always nice to see a submission with sources!
